Product Description
Fore Stern Tube Marine Bearing
Our INDRON® have been widely adopted in bulk carriers and working ships, successfully replacing metal stern bearings and rudder bearings in oil-lubricated systems. Compared to other non-metal stern and rudder bearings in water-lubricated systems, INDRON® bearings offer a longer service life, helping ship owners significantly reduce costs and enhance the reliability of stern and rudder bearing systems.
Fore Stern Tube Marine Bearing Key Advantages
INDRON® Fore Stern Tube Marine Bearings are engineered with an advanced elastomeric polymer alloy, offering a superior alternative to traditional Thordon SXL bearings. Designed to meet the rigorous demands of the marine industry, these bearings provide exceptional performance, durability, and environmental benefits.
Water Lubrication
Utilizing natural water as the lubrication medium eliminates the risk of oil or grease leakage, thereby preventing water source pollution.
Self-Lubricating and Maintenance-Free
The elastomeric polymer alloy incorporates long-lasting self-lubricating microcrystals and extreme pressure particles, ensuring low friction and high wear resistance. This design supports dry starts and reduces the need for regular maintenance.
Durable and Resilient
Capable of withstanding impact loads and edge loads, our bearings exhibit excellent wear resistance and can embed abrasive particles, preventing shaft surface damage.
Customized Solutions
We offer tailored material selection and bearing designs based on specific equipment characteristics and operating conditions, ensuring optimal performance for each application.
Certified Quality
Our products have received factory approval from the China Classification Society (CCS) and are ISO9001:2015 certified, reflecting our commitment to meeting and exceeding customer expectations.

Our laboratory is equipped with advanced material performance testing and analysis instruments, allowing us to strictly control every detail of product design and production, ensuring superior product quality. INDRON® bearings, seals, and gaskets are more durable than ordinary bearing materials under various conditions, including dry friction, water lubrication (clean water or water containing sand and mud), non-lubrication, grease lubrication, and even under impact load conditions.

Partial data from THORDON product description
Under the same conditions, INDRON® elastoplastic alloy has less wear than other common nonmetal bearing materials, and some of its models are even better than imported materials,which means INDRON® bearing has longer service life, higher reliability and lower maintenance cost.
Fore Stern Tube Marine Bearing Applications
INDRON® elastoplastic alloy bearings are ideal for various marine applications due to their wear resistance, corrosion resistance, impact resistance, and suitability for water lubrication. They are extensively used in:
●Cruises
●Deck machinery
●Yachts
●Sand carriers
